Developmental venous anomaly

Case contributed by Dr Mostafa El-Feky


Diminished vision of the left eye.

Patient Data

Age: 40 years
Gender: Male

CT brain

Two foci of confluent veins are seen at the left deep parietal lobe and the periventricular white matter they measure 2 mm, draining to the left internal cerebral vein. No related cortical abnormality noted.

Case Discussion

These prominent venous structures at the left parietal region along with prominent dilated draining vein and normal related brain parenchyma are likely representing developmental venous anomalies.

Developmental venous anomalies (DVA) represent variations of normal venous drainage rather than true malformations. They are usually asymptomatic. They consist of tortuous tributary veins that converge on an enlarged draining vein giving a "caput medusae" appearance.
